It is a misnomer to look for a professional and reliable fraud site.
As I tried to explain about two years ago, the OP obviously wasn't actually asking for a "reliable fraud site." He was simply asking for a legitimate company that might be most likely to deliver a good essay, despite the fact that no company always delivers satisfactory work on each and every project. The site(s) for which I wrote as a company writer were all legit, in that they never stole money from customers or blackmailed them or allowed writers to deliver plagiarized essays.They also required writers to provide rewrites anytime they failed to follow instructions and they always fully refunded customers for any projects that never got taken off the assignment board by any writer by their posted deadlines. So, in that sense, they were completely legitimate companies and not "fraudulent"; nevertheless, as I explained in my earlier post above, there were definitely instances when customers complained about receiving bad essays and, occasionally, I took projects that were clearly those customers' second attempts at ordering the same project, in which cases I got to see the terrible essays that they'd received the first time. There were also instances where writers got fired for plagiarism anytime it was caught by the company's scanner and/or anytime clients provided evidence to back up those kinds of complaints; and they definitely had some ESL writers on their roster whose writing I saw in some of those projects that were re-ordered.
Even a legitimate company sometimes gets duped by writers who submit phony samples or credentials (or who have someone else take writing tests for them) and whose work just isn't up to par, once they're hired. All they can do is fire those writers as soon as they discover that their writing isn't good. When a company maintains a roster of 100+ writers, some of them will always be much better than others and some of their hired writers are just trying this kind of job out for the first time without many projects under their belts, besides their own essays from college. Every essay company hires some writers who end up getting fired pretty quickly because their work just isn't good enough. That's obviously not much help to the customers whose projects are involved; but legitimate companies at least try to make good by issuing refunds or reassigning those projects. Legit companies respond to valid complaints appropriately and honor their posted guarantees. Fraudulent companies take customers' hard-earned money with no intention of ever actually delivering an essay, and/or they know that all of their writers just copy/paste from Wikipedia, and/or they use their customers' information to blackmail them into dropping completely legitimate complaints about unsatisfactory work. I believe that's the distinction that the OP was making and that he was simply asking for help finding a legitimate company instead of a fraudulent company, as I've defined and differentiated those two types of companies above, and not a "reliable fraud site."
